Embodiment Construction

[0024] Short fibers of chemical fibers with a linear density of 1 to 2.5 dtex (such as synthetic fibers such as polyester, polypropylene, acrylic, nylon, chlorine, vinylon, and nylon, or various viscose and acetate man-made fibers) After the raw materials are opened, mixed and carded, they are cross-laid into a chemical fiber web 1 (see the attached figure), and the surface density of the chemical fiber web 1 is 20-70g / m 2 . Then the surface density is 40~70g / m 2 The woven glass fiber mesh cloth 2 is sandwiched between the upper and lower chemical fiber nets 1, and after being pre-wetted with water, the upper and lower spunlaces are passed through the spunlace machine, so that the chemical fibers and glass fiber mesh cloth in the upper and lower chemical fiber nets 1 tangle. Sizing and dipping the spunlace blank with a binder (such as polyacrylate, polybutylacrylate, etc.), and then heating, drying, and heat setting to obtain the spunlace composite non-woven wall crack-proof...

Abstract

A spunlace composite non-woven wall anti-crack material, characterized in that: the material is a chemical fiber net formed by cross-laying upper and lower layers and a woven glass fiber mesh cloth sandwiched between the upper and lower chemical fiber nets A composite material that is spunlace and bonded. The invention solves the technical problems of simple and convenient material processing, suitable for large-scale production, good combination effect with wall body and paint, convenient construction and low reinforcement cost.

Description

Technical field: [0001] The present invention relates to building materials, in particular to hydroentangled composite non-woven materials for preventing cracks on walls. Background technique: [0002] Cracks on the wall are a common quality defect of buildings. They are caused by loads, changes in temperature and humidity, and uneven settlement during the construction and use of buildings. The factors that produce cracks are still difficult in the current technology. For this reason, people start with building materials and use suitable construction methods to prevent wall cracks. For example, cement composite reinforcing materials are currently used to prevent wall cracking, but it is required that the cement and reinforcing fibers be mixed very uniformly, otherwise it will seriously affect its anti-cracking effect, and it is very important to evenly distribute the easily entangled fibers in the cement slurry. Difficult, so the mixing and construction of materials are mor...
